COLLAPSIBLE BARREL.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Application filed December 2, 1916. Serial No. 134,691.

To all whom it may concern:

Be it known that we, SEWELL A. KNAPP, of Berkeley, county of Alameda, State of California, and Moses A. KNAPP, of Oakland, county of Alameda, State of California, citizens of the United States, have invented new and useful Improvements in Collapsible Barrels, of which the following is a specification.

This invention relates to collapsible sheet metal barrels; and has for its ob ect to simplify and improve the construction of same.

The invention in its present form comprises a barrel having a body portion conslsting of a single sheet of metal rolled cylindrical form with its longitudinal meetedges detachably held together 'by means b f hoops or hands, said sheet having end crozes to receive each a removable head, a split metal chine reinforcing ring for each end of the barrels held in place thereon by the outwardly folded edges of the cylinder, forming in conjunction with the adjacent crozes an annular pocket, said ring havin its portion opposite the split end Weaken to perinit spreading apart of the ends, whereby the barrel sheet may be nested when in collapsed form, and easily separable means for fastening together the meeting ends of the chine ring and fold.

form which our invention may assume is exemplified in the following description and illustrated in the accompanying drawings, in which Figure 1 shows a cross section of an ed of the. barrel, illustrating the head, t e chine and barrel croze.

Fig. 2 shows the same section through a thinned and bendable portion of the c inc reinforcing ring.

Fig. 3 shows an elevation of a portion of the barrel, illustrating the tie for the ends of the chine reinforcing ring.

Fig. 4 shows in plan a thinned and bendable portion of the chine reinforci rmg.

Fig. 5 shows a plan of the chine reinforcing ring with the tie at the ends and one bendable portion.

Fig. 6 shows an assembled barrel.

Referring more in detail to the form illustrated, we show a barrel comprising a sheet metal body portion 10, rolled into cylindrieel form with one of its longitudinal edges provided with a pocket 11, to receive the conjunction with a to bend readily at this opposite edge; suitable packing being inserted in the joint to prevent leaka e of the contents. Near each end of the cylinder is an outwardly expanded croze 12, to receive a removable head 13 of suitable form, and at points intermediate the crozes and adjacent thereto, the sheet metal is grooved to receive tie Wires or bands 14, the ends of said tie wires being connected together in any. suitable way, but preferably by means of a staple 15 similar to staple 19 passing through the looped ends 16 of the wire.

At each end of the barrel, adjacent to ,croze 12 is a chine 17, formed by folding tl1e edge of the sheet outwardly to form in the croze an annular pocket to receive a split ring 18. As shown 1n Fig. 3, the ends of the chine fold and ring are not overlapped, but are held in po sition by means of a staple or tie 19 passlng through opienings20 in the chine fold and the ring. he lower edge of the chine reinforcing ring rests upon and is supported by the upper edge of the adjacent croze, the latter in effect closing the channel formed by the folded edge of the body portion. The staple 19 is capable of quick detachment and makes a strong fastener for the split ends of the chine, thereby preventing the head 13 from becoming displaced.

On chine reinforcing ring 18, preferably at a point opposite the split ends, is a thinned portion 21 which permits the ring point, suflicient strength being retained to hold the barrel head in place and resist all ordinary strain on the chine. By having this thinned portion the ring yields readily to ermit separate movement of the free ends t ereof when the barrel is in collapsed position, so that a number of barrels may be nested one within the other.

e advantages of the described construction reside more particularly in the use of a split reinforcing chine fold and chine ring held together at their meeting ends by means of an easil separable fastener; the use of an outwar fold on the chines of the body portion to form an annular pocket for the chine ring whereby the outwardly expanded croze will cooperate therewith to retain the chine reinforcing ring inpIace, and also in the use of a chine reinforcing ring having a weakened or thinned portion opposite the cylindrical sheet metal body portion desplit ends to permit separating movement of the ring for nesting a plurality of barrels.

It is important that the chine of the barrel should be securely held against any outward movement in order to prevent any possibility of the head being dislodged, and inasmuch as the nearest band or tie wire 14 is below the head, suitable fastening means must be provided for the meeting ends of the chine fold and chine reinforcing ring. Should the circumferential ends of the sheet metal body he turned inwardly instead of outwardly to form the pocket for the chine reinforcing ring the cooperation of the croze 12 would be lost and no convenient means would be present for retaining the rin in place within the pocket.

'I he manner of assembhn and colla sing the barrel is believed to be 0 vious. T e assembly is accomplished by putting the tie wires in lace within their grooves and fastening t eir looped ends together through the agency of the staples 15 and connectlng the split ends of the chine reinforcing rings with the fastening means 19. The collapsin of the barrel can be quickly accomplished by disconnecting or separating the fasteners or staples 15 and 19.

Various changes in the construction and arrangement of the several parts herein shown and described may be employed without departing from the spirit of our invention, as disclosed in the appended claims.

Having thus described our invention what we claim and desire to secure by Letters Patent is:

1. A knock-down metal barrel comprising a cylindrical sheet metal body {{OltlOIl the contiguous edges of which inter ock lon tudinally, a croze formed at each end of t e body portion, a removable head seated within each croze tie wires adapted to securely bind the b0 y portion around the heads and a reinforcing ring adapted to be secure around the outer faces of the heads to further prevent the removal thereof.

2. A knock-down metal barrel comprising a sheet metal cylindrical body portion detachably joined longitudinally, a croze at each end of the body portion, a removable head in each croze, easily separable means intermediate the crozes for retaining the lon 'tudinal ends of the body portion toget er, a split chine adjacent each croze, a split reinforcing ring therein, said ring having a thinned portion opposite the split ends to permit separatin movement thereof when the barrel is col apsed, whereby to" ineet a plurality of barrels.

3. A knock-down barrel comprising a tachably joined lon 'tudinally, a croze formed in each end 0 the body portion, a

chine formed at each end of the body portion by overturnin the marginal edges of the sheet metal bo y around the outer circumference of the body portion, a rigid chine reinforcing ring adapted to be POSI- tioned within each of the chines, said chines and rings having separable ends andmeans whereby said rings and chines may be detachably secured at their separable ends.
